ABSTRACT

Teacher support for students in ubiquitous learning environments is challenging owing to physical distance and a lack of reliable real-time multimedia-rich communication. This is further complicated because the learning process is dynamic and problems need quick resolution. Given these challenges, this study proposes an architecture for a teacher facilitation support system. The system was implemented in the form of an interactive teacher dashboard. The interface also generates possible solutions to learning challenges while leaving the ultimate decision up to the teacher. The system feasibility was tested by work-through scenarios designed and validated by two experts. The system usability was evaluated using the System Usability Scale by 40 potential users. The ?ndings revealed that the dashboard has good feasibility and usability for providing teachers relevant information about their students’ learning progress in ubiquitous learning environments. It also enabled opportunity for pedagogical intervention when needed.  相似文献

This paper introduces the basics of a (psycho)linguistically-oriented model of language-training competences of educators in pre-school and elementary education. It specifies competence criteria for language intervention based on psycholinguistic research. Ultimately, these criteria will be useful for grounding the additional training of educators and for certifying competences in early language intervention.  相似文献

Abstract

Juvenile obesity is increasing worldwide. Preventive strategies are warranted. The school-based Children's Health Interventional Trial (the CHILT Project) combines health education and physical activity for children. The effect on obesity and physical performance was studied after four years in 12 primary schools compared with five control schools. Anthropometric data were recorded. Physical performance was measured by a coordination test for children (balancing backwards, one-legged obstacle jumping, lateral jumping, sideways movements) and a 6-min run (endurance). No difference in the prevalence and incidence of overweight and obesity was found between the intervention and control schools before and after the intervention. Remission of overweight was higher in the intervention schools (23.2 vs. 19.2%), but not significant. An increase in coordination related to lateral jumping and balancing backwards was apparent in the intervention schools (30.6, s = 10.8 vs. 26.1, s = 10.8, P = 0.005; 21.8, s = 11.8 vs. 19.4, s = 11.7, P = 0.007), and the increase in endurance performance tended to be higher in intervention schools (100.8, s = 122.7 vs. 92.8, s = 126.0, P = 0.055), adjusted for age, sex, baseline test result, and body mass index at final examination. Therefore, preventive intervention in primary school offers the possibility to improve physical performance in children. The prevalence and incidence of obesity were not affected.  相似文献   

Coping with mismatched courses: students’ behaviour and performance in courses mismatched to their learning styles     

Kinshuk  Tzu-Chien Liu  Sabine Graf 《Educational technology research and development : ETR & D》2009,57(6):739-752

Although learning styles are considered as an important factor in education, students often have to learn in courses that do not support their learning styles. A challenge for technology facilitated learning is therefore to assist and help students to cope with courses that do not match their learning styles by training and developing their less preferred skills. In this paper, the interactions between students’ learning styles, their behaviour, and their performance in an online course that is mismatched regarding their learning styles were analysed. The results show which learners need more help in mastering mismatched courses, help in getting a better understanding about how students with good performance record and poor performance record learn with respect to their learning styles, and provide information about how to identify learners who might have difficulties in learning based on their behaviour.  相似文献   

Specific managerial human capital,firm age,and venture capital financing of biopharmaceutical ventures: A contingency approach     

Judith Behrens  Holger Patzelt  Lars Schweizer  Robin Bürger 《The Journal of High Technology Management Research》2012,23(2):112-121

In this article we investigate how specific human capital in biopharmaceutical ventures' management teams impacts the financial commitment of venture capital investors. Further, we explore how this impact changes with the venture's age. We draw on data from 138 VC financing rounds in the US and Europe to show that biopharmaceutical ventures with greater portions of specific managerial human capital in the fields of management, law, medicine, and biosciences acquire more money in venture capital financing rounds, but this effect is contingent on the age of the venture. We discuss the implications of these findings for the literature on VC financing of high technology ventures.  相似文献

Konzeptueller und logischer Data-Warehouse-Entwurf     

Holger Schwarz 《Informatik - Forschung und Entwicklung》2004,18(2):53-67

Zusammenfassung. Im Data-Warehouse-Bereich gibt es sowohl auf der konzeptuellen als auch auf der logischen Ebene unterschiedliche Modellierungsansätze, deren Entwicklung sich in der Regel an typischen Fragestellungen aus dem Bereich des Online Analytical Processing (OLAP) orientierte. Daneben spielen aber auch andere Ansätze zur Analyse der Daten in einem Data Warehouse eine bedeutende Rolle. Ein wichtiger Vertreter ist Data Mining, mit dessen Hilfe bislang unbekannte Muster und Zusammenhänge in Daten identifiziert werden können. Im vorliegenden Artikel wird untersucht, inwieweit sich die in der Literatur vorgeschlagenen konzeptuellen Datenmodelle für ein Data Warehouse eignen, das OLAP- und Data-Mining-Analysen gleichermaßen unterstützt. Hierzu wird das COCOM-Modell, das auf den Modellierungsmöglichkeiten verschiedener publizierter Modelle aufbaut, vorgestellt und bewertet. Für das logische Schema eines Data Warehouse wird häufig ein sogenanntes Star-Schema oder ein Snowflake-Schema erstellt. Für diese und weitere Schematypen wird analysiert, welchen Einfluss die Wahl des logischen Schemas auf Anwendungen aus den Bereichen OLAP und Data Mining hat. Wichtige Kriterien sind hier unter anderem der Informationsgehalt und die Performanz. Insgesamt zeigt dieser Beitrag, dass das COCOM-Modell und das Star-Schema eine gute Grundlage für den integrierten Einsatz von OLAP und Data-Mining bilden.Eingegangen am 30.
